' ILIFTON S. HUNT, OF MODOC, INDIANA.

ROAD-SCRAPER.

SPECIFICATION formingpart of Letters Patent No. 791,789, dated June 6,1995.

Application filed February 27, 1905. Serial No. 247,576.

To a. whom it may concern.-

Be it known that I, GLIn'roN S. HUNT, a citizen of the United States,residing at Modoc,

in the county of Randolph, State of Indiana, have invented certain newand useful Improvements in Road-Scrapers, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a road-scraper, and particularly to aconstruction to prevent the lateral displacement of the frame of themachine due to the diagonal disposition of the scraper-blade.

The invention has for an object to provide the frame at its frontportion with a diagonally-disposed scraper-blade and at the rear with atrailer-blade disposed at an angle to the scraperblade, so as to resistdisplacement of the frame.

A further object of the invention is to provide means for drawing thescraper and trailer blades toward each other, thus obtaining a deepergrip of the latter and'throwing the weight of the frame thereon. 1

Another object of the invention is to provide an improved means foradjusting the scraper-blade and retaining it in its adjusted 5 to by alink-joint 0 position for different conditions of use.

Other and further objects and advantages of the invention will behereinafter set forth, and the novel features thereof defined by theappended claims.

In the drawings, Figure 1 is a perspective of the invention, and Fig. 2a longitudinal section upon the line 2 2 of Fig. 1.

Like letters of reference refer to like parts in both figures of thedrawings.

The letter A designates the platform or frame of the machine, which issuitably supported upon the axle A, provided with wheels A, by which itis supported. Beyond these wheels rearwardly-extending brace-rods A aredisposed and connected to the frame at A. These rods are also providedwith an angularly-disposed portion A lying in a vertical plane, to whichthe trailer-blade B is secured.

-At the front of the frame a scraper-blade C,

ofany desired material, is disposed and is supported by means of a leverC, connected there- This lever is pivotally tion shown by dotted linesin Fig. 1, and thushold the free end of the lever in raised position toretain the scraper-blade in contact with the ground.

Any suitable draft means may be supplied to the machine-for instance, apole, as shown at C connected by rodsC with the scraperblade to applythe draft directly thereto. The draft is communicated from the blade Cto the axle of the machine by means of links D and D, each of which isprovided at one end with a collar D to fit upon the axle and at itsopposite end with a swivel connection with the scraper-blade of anydesired constructionf0r instance, as shown at D. This swivel connectionpermits a longitudinal inclination of the blade for the purpose ofditching or cleaning ditches already formed, and the blade may besoinclined by means of the operating-lever D, pivotally mounted at D uponthe upper end of the standard D", extending from the axle and connectedat its outer end D with one end of the scraper-blade, so as to elevatethat end when the free end of the lever D is depressed.

For the purpose of drawing the scraper and trailer blades toward eachother and thus cause a deeper hold of the latter in the ground, thusrestraining the tendency of the frame to a lateral displacement, theseblades are connected together by rods B and B connected to any suitableform of lever adapted to produce a simultaneous draft in the samedirection upon each of the rods. 1 have shown one form of lever adaptedfor this purpose comprising the cramp lever B, pivotally mounted at B ina bracket B and adapted to be held at its adjustment by means of thelatch 13, engaging the ratchet-segment B upon the upper surface of theplatform. It will be obvious that a movement of this lever will producea strain upon the rods drawing the scraper and trailer blades towardeach other, thus forcing the same downward and removing the weight tosome extent from the tractionwheels in order to obtain a better anddeeper hold upon these blades to resist the lateral displacement causedby the diagonal disposition of the scraper-blade.

It will be obvious that changes may be made in the details ofconstruction and configuration without departing from the spirit of theinvention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim,and desire to secure by Letters Patent, is-

1. In a road scraper, a frame supported upon an axle having wheels, adiagonally-disposed scraper-blade at the front of said frame andconnected to said axle, and a trailer mounted upon the rear of saidframe at an angle to the scraper-blade.

2. In a road-scraper, a frame, a diagonallydisposed scraper-blade at thefront thereof, a trailer-blade at the rear of said frame disposed at anangle to the scraper-blade, and means for drawing said blades towardeach other.

3. In a road-scraper, a frame, a diagonallydisposed scraper-blade at thefront thereof, a trailer-blade at the rear of said frame disposed at anangle to the scraper-blade, means for drawing said blades toward eachother, and means for elevating and retaining said scraperblade.

4. In a road-scraper, a frame, a diagonallydisposed scraper-blade at thefront thereof, a trailer-blade at the rear of said frame disposed at anangle to the scraper-blade, means for drawing said blades toward eachother, means for elevating and retaining said scraper-blade, and meansfor elevating one end of said scraper-blade.

5. In a road-scraper, a frame, adiagonallydisposed scraper-blade at thefront thereof, a trailer-blade at the rear of said frame, a crampleverupon said frame, and connections from said cramp-lever to each of saidblades.

6. In a road-scraper, a frame, a diagonallydisposed scraper-blade at thefront thereof, a trailer-blade at the rear of said frame, a crampleverupon said frame, connections from said cramp-lever to each of saidblades, and means for retaining said lever in its adjusted position.

7 In a road-scraper, a frame, a supportingaxle, traction-wheels for saidaxle, a scraperblade pivotally mounted at the front of said frame bylinks extending from said axle, a raising-lever for said blade, and arack-bar for retaining said lever in position.

8. In a road-scraper, a frame, a supportingaxle and traction-wheelstherefor, a scraperblade pivotally mounted at the front of said frame bylinks extending from said axle, a raising-lever for said blade, arack-bar for retaining said lever in position, and a pivotal support forthe lower end of said rack-bar to permit the same to swing into contactwith said lever when its free end is depressed.

9. In a road-scraper, a frame provided with an axle and traction-wheels,a scraper-blade disposed at the front of said frame, links pivotallymounted at one end upon said axle, and a swiveled joint between theopposite end of said links and the scraper-blade.

10. In a road -scraper, a frame provided with an axle andtraction-wheels, a scraperblade disposed at the front of said frame,links pivotally mounted at one end upon said axle, a swiveled jointbetween the opposite end of said links and the scraper-blade, and anoperating-lever pivotally supported upon said axle and connected at oneend of said blade to elevate the same.

In testimony whereof I afiix my signature in presence of two witnesses.
